One of sour sodium, sodium carbonate are a variety of.
The invention also discloses a kind of physical blowing Muddy Bottoms lightweight solidified earth preparation methods, comprising the following steps:
(1) preparation of mud mud: original state mud and water are weighed in proportion to agitating device, stirs 6~10min, preparation
Mud mud is stand-by out, and mud stands the resting period no more than 30min；
(2) preparation of foaming agent water solution: being weighed whole water by configuration proportion, by load weighted sodium carboxymethylcellulose
It is sufficiently stirred and is dissolved in the water, static 5min, is added alkyl phenol polyoxyethylene ether and animal protein class foaming agent persistently stirs
5min, be eventually adding lauryl sodium sulfate persistently stir 8~10min just complete foaming agent water solution preparation；
(3) preparation of foam: injecting foam device for prepared foaming agent water solution, control blow pressure, by 30~
35 expansion ratios prepare foam, and the foam the prepared independent resting period is not preferably greater than 10min；
(4) preparation of the light matter solidified earth of foamed sludge: mud mud, curing agent, thinner are disposably weighed in proportion
And early strength agent, 2min is first stirred with the revolving speed of 50 ± 5r/min, 2min is then stirred with the revolving speed of 120 ± 5r/min again, finally
The foam of step (3) is added, 5min is stirred with the revolving speed of 50 ± 5r/min, completes the preparation of lightweight solidified earth, the solidification of this lightweight
Soil can be used for engineering construction.
Technical principle: lauryl sodium sulfate and alkyl phenol polyoxyethylene ether expansion ratio are higher, the foaming of animal protein class
The foam stability that agent is prepared is good, and above foaming agent compound use can be prepared that expansion ratio is moderate, and foam stability is good
Foaming agent, while the sodium carboxymethylcellulose of instant thickening function is added, further enhances foam stability, extend bubble
Foam half-life period can reduce the rupture decaying of subsequent mixing process foam.
The preparation process of lightweight solidified earth is the mechanical blending process of mud mud, curing agent and foam, and use is lower
Mixing revolving speed stirs evenly the above substance, and foam is made to be dispersed in solidified earth system, forms round closed independent air bubble one by one
Space, bubble outside are mud and curing agent mixture slurry, and the substances such as moisture and soil body particle occur one in curing agent and mud
The aquation of series, hydrolysis, generate a large amount of hydrated gel product, constantly reinforce bubble outer space, form one by water
Change gel be wrapping layer, the honeycomb structure that bubble is skeleton, have some strength and stability while, the quality of solidified earth
Also relatively light.It newly mixes in lightweight solidified earth system, because of the ball effect of bubble, makes newly to mix lightweight solidified earth with good flowing
Property, it is suitable for pumping, can be applied to the backfill construction of the concealed works such as piping lane and pipeline, increases the density of the backfill earthwork.Gently
It is honeycomb structure after the hardening of matter solidified earth, the presence of internal a large amount of bubbles makes solidified earth have good damping and uniform heavy
Effect is dropped, can be used as highway subgrade and abutment filler material.
The present invention has the advantage that
